                                                                                                  AD8305ACPZ-RL7 is an inexpensive microminiature logarithmic converter optimized for determining optical power in fibre optic systems. It uses an advanced implementation of a classic translinear (junction-based) technique to provide a large dynamic range in a versatile and easily used form. A single-supply voltage of between 3V and 12V is adequate; dual supplies may optionally be used. The low quiescent current (typically 5mA) permits use in battery-operated applications. The input current, IPD, of 10nA to 1mA applied to the INPT pin is the collector current of an optimally scaled NPN transistor, which converts this current to a voltage (VBE) with a precise logarithmic relationship. A second such converter is used to handle the reference current (IREF) applied to pin IREF. Applications include optical power measurement, wide-range baseband logarithmic compression, measurement of current and voltage ratios, and optical absorbance measurement.
